But that does not work and I have been told that this problem is not caused by Acronis TI 11 Home but is , instead, a problem with my hard drive. However, other backup software (Shadow Protect and Vista's own backup software) both work without a hitch and so, clearly, my hard drive is NOT the cause of this particular problem.
